Shares traded as high as $15.71 during the day, with the marketing closing at $15.22. After hours trading is also around $15.36.

Analyst Sterne Agee’s Arvind Bhatia added that shares could go even higher if next week’s trailer announces a release date for the game:

Still, if Rockstar announces the official release date for the title, in conjunction with the release of the trailer, we think it will be positive for the shares.

Bhatia’s firm expects GTA V to sell 25 million units – 3 million more more than the 22 million that Grand Theft Auto IV has sold, which seems surprisingly conservative considering how much the HD console install base has grown since GTA IV released.

GTA V‘s first trailer is set to release on November 2nd, and will hopefully include gameplay footage of the game, as well as a release date (or even just a release year).
